UNITED STATES PATENT OEEIoE JAMES ADAIE, or PITTSBUEG, PENNSYLVANIA.

IMPROVEMENT IN PAPER-FILES.

Specification forming part of Letters Patent No. 72,711, dated December 31, 1867.

To all whom it may concern:

Beit known that I, JAMES ADAIR, of Pittsburg, in the county of Allegheny, in the State ot Pennsylvania, have invented a new and Improved Mode of Making Paper-Holders; and. I do hereby declare that the followingjs a full and exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereoml The nature of my invention consists in providing a paper-holding spur, intended for permanent attachment to a desk or other suitable object, with cheap and ready means of making such attachment, and also in providing it with a device for pressing the papers down upon it and holding them there, the whole constituting a superior paper-holder.

This paper-holder is made up of four pieces ot' wirea bow, a spur, a presser, and aspiral spring. The bow a b c d has a thread cut upon it atthe part a, so forming a screw, and in the usual manner, on a suitable mandrel,is closely coiled into a spiral at the part b, so forming a spur-seat. It is then extended, bent, and again extended, so forming a guide, c; is bent again, is again extended, and formed'into a closely-coiled spiral at d, so forming a presser-sleeve. The spur c is sha-rpened at one end, and has its other end or base enlarged by flattening it, in which condition it is driven, point. foremost, into the spur-seat b, the enlarged end or base binding within the spiral seat, thus irmly holding the spur toits place. The presser f g h i has a hook formed at the end f, and turned over the guide c, and also has a spiral ring at the part g. Its stem h, passing thence through the sleeve d, is then provided with a ring, The hook atf, loosely embracing the guidec, prevents the presser turning in its sleeve d, while this sleeve sodirecls the presser, which slides neatly within it, that its ring g is centrally pierced by the spur e. The spiral spring k, madein the usual manner with its coils apart., is screwed on to and encircles the guide c, and bears against the sleeve d and against the hook at f.

v The instrument operates as follows: After screwing it into a desk, forinstance, by means of the screw a, the 'ring c' is grasped and drawn backward, causing the presser to v-recede from the spur, to the point of which a paper is applied, whereupon the presser is released, and, actuated by the spring, it drives the paper upon the spur and holds it there.

, Wha-t I claim as my invention, and desire to secure by Letters Patent, is-

lhe paper-holder, as a new article of manufacture, constructed substantially as described.
